The variants included in the database were derived from the published literature and, where necessary, annotated to conform to current HGVS mutation nomenclature. (Note: Some variants have not yet been definitively assigned to a standard location due to the use of differing/unclear nomenclature amongst authors.) The HGVS recommended cDNA numbering starts from the first ATG of the full coding sequence. Protein reference sequences should represent the primary translation product, not a processed mature protein, and thus include any signal peptide sequences. When you notice any omissions or mistakes, please let us know (thank you).
